WALTER T. SCOTT, OF SIOUX FALLS, SOUTH DAKOTA.

CHIIENEY THIMBLE.

Application filed April 20, 1925. Serial No. 24,504.

T 0 all whom it may concern:

Be it known that I, IVALTER l.' Ecorr, a citizen of the United States, residing at Sioux Falls, in the county of lifinneliaha and State of South Dakota, have invented certain new and useful Improvements in Chimney Thimbles, of which the following is a specification.

This invention relates to certain new and useful improvements in chimney thimbles and the primary object thereof to provide improved means for effectively connect-- ing the thimble to the chimney, which means more particularly is of simple and economical construction, enabling the secure ment of the thimble, easily and quickly.

The invention still further aims to provide connecting means which limits the inward movement of the stove pipe into the thimble, thereby to prevent the pipe from shutting off the draft, and still further aims to provideconnecting means which involves a minimum of parts, that are compactly assembled.

In the drawings:

Figure 1 is a front elevation of the device in position in a chimney;

Fig. 2 is a rear elevation of the device;

Fig. 3 is a section on line 33 of Figure 1, and

Fig. 4; is a detail perspective view of one of the clamping jaws.

In proceeding in accordance with the present invention, a face plate 1 is provided having a rearwardly tapering thimble 2 cast integral therewith, and formed of a length to have its rear end extend beyond the rear face of the chimney wall C. The face plate 1. has diametrically opposed openings 3 to receive bolts 4, the latter be ing disposed on the exterior of the thimble so as to be protected by the latter and by the chimney wall as depicted in Figure 3.

A pair of clamping jaws 5 are employed and which are longitudinally channeled having U-shaped bends 6 to receive and engage over the rearwardly projecting end of the thimble. The jaws are further formed with openings 7 to receive the bolts 4.

In operation, the thimble 2 is inserted in the chimney opening and with the face plate 1 engaged with the front face of the chimney. The jaws 5 are seated fiat against the rear face of the chimney and the bolts are then inserted through the registering openings 3-and 7, whereupon the nuts are tightened to cause the jaws to firmly clamp the thimble inplace.

The inner. ends 8 of the jaws, it-will be noted, areextended to form stops or abutment-s which project into the interior of the thimble to an extent to. engage the inner end of the stove pipe (not shown) thereby to prevent said end from entering the chimney and cutting off the draft.

hat is claimed is:

1. In combination with a thimble having a face plate formed to engage the front face of a chimney wall and having its rear end projecting beyond the rear face of the chimney, jaws having free outer ends formed to seat on the rear face of the chimney wall and'having inner ends with U-shaped bends therein receiving and seated on the said rear end of the thimble, and bolts extended through the face plate and through the jaws and disposed exteriorly of the thimble, the inner ends of the jaws being extended to project into and register with the interior of the thimble to form stops to engage the stove pipe to prevent the latter from entering the chimney flue.

2. Incombination with a thimble having a face plate formed to engage the front face of a chimney wall and having its rear end projecting beyond the rear face of the chimney, jaws having free outer ends formed to seat on the rear face of the chimney wall and having inner ends with U-shaped bends therein receiving and seated on the said rear end of the thimble, and bolts extended through the face plate and through the jaws.

3. In combination with a thimble having a face plate formed to engage the front face of a chimney wall and having its rear end. projecting beyond the rear face of the chimney, jaws having free outer ends formed to seat on the rear face of the chimney wall and having inner ends with U-shaped bends therein receiving and seated on the said rear end of the thimble, and bolts extended through the face plate and through the jaws, said bolts being disposed between the exterior of the thimble and the adjacent portions of the chimney.

4. In combination with a thimble having a face plate formed. to engage the front face of a chimney wall and having its rear end formed to project rearwardly of the wall, jaws having free outer ends engageable with the rear face of the wall, and hav-,

ing inner ends seated on the projecting end of the thimble, and means connected to the face plate to clamp the jaws against the rear end of the thimble.

5. In combination with a thimble having a face plate formed to engage the front face of a chimney wall and having its rear end formed to project rearwardly of the wall, jaws having free outer ends engageable with the rear face of the wall, and having inner ends seated on the projecting end of the thimble, and bolts disposed exteriorly of the thimble and connected to the jaws and to the face plate to clamp the jaws against the rear face of the wall.

6. In combination with a thimble having a face plate formed to engage the front face of a chimney wall and having its rear end formed to project rearwardly'of the wall, jaws having free outer ends engageable with the rear face of the wall, and having inner ends seated onthe projecting end of the thimble, and means connected to the thiinble to secure the aws in place, said jaws having parts which register with the thimble interior to form stops to engage a stove pipe thereby to prevent the pipe from entering the chimney flue.

7. In combination with a chimney thimble having a face plate engageable with the front face of the chimney wall and with the rear end of the thimble formed so as to project adjacent to the rear face of the wall, means having free outer ends to engage the rear face of the wall and having inner ends seated on the rear end-of the thimble and formed to project into register with the interior of the thimble to form stove-pipe engaging stops, and means to secure the combined means tothe thimble.
